Explanation:
Khyber Pass, Khyber also spelled Khaybar, orKhaibar, most northerly and important of the passes between Afghanistan and Pakistan. The pass connects Kābul with Peshāwar. The pass has historically been the gateway for invasions of the Indian subcontinent from the northwest. The name Khyber is also applied to the range of arid, broken hills through which the pass runs and which form the last spurs of the Spin Ghar (Safīd Kūh) Range. On either side of the connecting ridge are the sources of two small streams, the beds of which form the Khyber gorge. This narrow gorge forms the Khyber Pass; it winds between cliffs of shale and limestone, 600–1,000 feet (180–300 m) high, and enters the Khyber Hills from the Shadi Bagiār opening, a few miles beyond Jamrūd, Pak., and continues northwestward for about 33 miles (53 km). Just beyond the old Afghan fort of Haft Chāh, it opens onto the barren Lowyah Dakkah plain, which stretches to the Kābul River.
The Northwest Passage is a sea route that connects the Atlantic and Pacific Oceans through the Canadian Arctic Archipelago. In the past, the Northwest Passage has been virtually impassable because it was covered by thick, year-round sea ice.
